A wastewater treatment system is disclosed that includes a desanding hydrocyclone, a deoiling hydrocyclone, an electrocoagulation apparatus that is adapted to receive a flow of treated wastewater from the desanding and deoiling hydrocyclones, a floc separator that is adapted to receive a flow of a first effluent from the electrocoagulation apparatus, and an ultrafiltration membrane apparatus that is adapted to receive at least a portion of a flow of a second effluent from the floc separator.

Systems and methods for treating oilfield wastewater

A method for coalescing a disperse phase component in a primarily gas process fluid includes passing the process fluid through a structure. The structure includes an outer wall with an electrically insulating material formed on an entire inner surface of the outer wall to define an entirely insulated flow path for receiving the process fluid and the flow path is free of any portion of the structure. A plurality of planar, spaced-apart electrode plates is positioned within the entirely insulated flow path and positioned substantially parallel to one another and substantially the entirety of each of the plurality of electrode plates is coated with an insulative material. At least one insulating member disposed in a space between and spaced apart from two adjacent electrode plates. A power source is applied to the electrode plates to generate an electrical field to coalesce droplets of the disperse phase component.

Separating primarily gas process fluids in an electrostatic coalescer

An electrostatic coalescer includes an outer wall defining a flow path for receiving a process fluid. A plurality of electrode plates is disposed within the flow path. A controller includes an inductor and a signal generator. The inductor is coupled in parallel with the plurality of electrode plates. The inductor and the plurality of electrode plates define a resonant circuit. The signal generator is coupled to the plurality of electrode plates and operable to apply an alternating current signal to the plurality of electrode plates at a frequency corresponding to a resonant frequency of the resonant circuit in the presence of the process fluid. The signal generator varies the frequency of the alternating current signal based on a positive feedback signal received from the resonant circuit to maintain resonance.
